## Homework Statement

A dead battery is charged by connecting it to the live battery of another car with jumper cables. Assume that V = 5.5 V and R = 0.50 .

What is the current of the starter and the current of the dead battery?

## Homework Equations

I=V/R, I1=I2+I3, basically Kirchoff's law...

## The Attempt at a Solution

I thought for finding the current of the starter all, you had to do was use I=V/R, so it would 5.5/.50, but it came out wrong :(. I then tried multiplying the two resistances together..still no luck, and did V/R..still no luck, however I found that the answer comes out to be 170-171, and how I have no idea how to get that. I also tried finding the current and then subtracting it from the intial voltage and divide by the intial resistance..when I did that, I got somewhere in the 100's, but no where near the answer. I came up with millions of techniques, but none worked. Can someone help? I'm really stuck on this.
